Biology Chapter 8

Front 1

Autotroph

Back 1

An organism that produces its own food

Front 2

Heterotroph

Back 2

An organisms that obtains energy from the food it consumes

Front 3

Adenosine Triphosphate (ATP)

Back 3

One of the principal chemical compounds living things use to store and release energy

Front 4

Photosynthesis

Back 4

Process in which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

Front 5

Pigment

Back 5

Light-absorbing molecule

Front 6

Chlorophyll

Back 6

Principal pigment of plants and other photosynthetic organisms; captures light energy

Front 7

Thylakoid

Back 7

Saclike photosynthetic membrane found in chloroplast

Front 8

Photosystem

Back 8

Light-collecting units of chloroplast

Front 9

Stroma

Back 9

Region outside the thylakoid membranes in chloroplast

Front 10

NADP+ (nicotinamine adenine dinucleotide phosphate)

Back 10

One of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules

Front 11

Light-dependent reactions

Back 11

Reactions of photosynthesis that use energy from light to produce ATP and NADPH

Front 12

ATP synthase

Back 12

Large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP

Front 13

Calvin Cycle

Back 13

Reaction of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
